"I always have a Varios PICO in my car. Thus I always have the perfect solution at hand if the customer has a broken pump."

The Wilo-Varios PICO Sync function:

The Wilo-Varios PICO includes a variety of pumps and their individual pump curves. The pump curve of the pump to be replaced can be reproduced by the Sync function using the Sync function Assistant here or in the Wilo-Wilo-Assistant App.

As today with Yonos PICO or Stratos PICO, Varios PICO can be used as replacement pump for comparable products from Grundfos, DAB, Lowara, KSB etc.

But only when replacing Wilo-pumps, the additional feature “Sync function” can be used to increase compatibility.

These includes the stand alone pumps Wilo-Star RS, Wilo-Stratos ECO, Wilo-Yonos PICO, Wilo-Stratos PICO and the integrated pumps Wilo-Yonos PARA, Wilo-PARA RS, Wilo-Yonos PARA RKC, Wilo-Yonos PARA RKA and Wilo-Yonos PARA PWM.

In doubt please refer to the product list in the Sync function tool.
